    Abstract: A hydrostatic advanced low leakage seal (100) configured to be disposed relatively rotatable components includes a base (107). The seal also includes a shoe (108) extending circumferentially. The seal further includes a beam (116) operatively coupling the shoe to the base, the beam having a beam length (L) that is substantially equal to or greater than a circumferential pitch of the shoe (108).

    Abstract: The present disclosure relates to advanced materials, particularly single crystal grain structures including the formation of single crystal grain structures. Single crystal grain structures offer improved mechanical properties when used with individual components. Improving mechanical properties is favorable for components that are used in applications with high temperature, pressure, and stress. In these applications, mechanical failure is extremely undesirable. Individual components, such as seals, can be designed with a single crystal grain structure in a preferred direction. By selecting a preferred direction, and orienting the single crystal grain structure accordingly, the single crystal grain structure can improve the component's mechanical properties. Single crystal grain structure seals and the method of forming the seals, therefore, offer various improvements to individual components, specifically when the components are designed for high temperature, pressure, and stress applications.
